Pedestrian crossing represents a substantial problem. In Iraq, there are no spaces marked specifically for pedestrians, which causes many conflicts between vehicles and pedestrians that lead to many accidents. The pedestrian death rate has increased recently due to the deficiency in adequate pedestrian infrastructure. However, to date, limited research has measured pedestrian behavior at crossing intersections in Iraq. There is a need to carry out in-depth studies to analyze crossing behavior to increase traffic efficiency and pedestrian crossing safety. Pedestrian crossing behavior is a serious issue to be addressed to provide adequate pedestrian facilities to enhance the pedestrian traffic environment. Road safety can be improved by locating crossing locations at the right locations and enforcing laws for pedestrian crossing. This study analyzes pedestrian crossing behavior in Baghdad City, Iraq, for four intersections at an unmarked crossing in the Central Business District (CBD) area. All required data were collected by video recording and a field questionnaire. Then, the data were extracted from video recordings and classified according to the selected variables. The period for observing the behavior was during the morning peak hours (November; time: 8:00 to 9:00 a.m.) for three days per week during normal conditions. This study examines pedestrian characteristics, vehicle/pedestrian flow characteristics, and traffic environment. Crossing patterns were followed for different gender and age groups. The finding reveals that the mean pedestrian speed is 1.33 m/sec. Also, males have a higher speed than females. The influences of age, gender, group size, and road width significantly affected pedestrian speed. The pedestrian speed decreased as pedestrian age increased. Gender and group size had significant effects on distinct crossing speeds. In addition, there is a weak significant correlation between pedestrian speed and selected variables. The study recommended specific marked places where a pedestrian must be located, and according to the pedestrian speed estimated in this study, a signal control for a pedestrian is recommended to be set up beside the street to organize the crossing with appropriate time for crossing safely.

Prędkość pieszego jest niezbędnym parametrem potrzebnym w większości analiz wyników rekonstrukcji zdarzeń drogowych z udziałem pieszego. W dostępnej literaturze znajdują się wyniki badań prędkości pieszych z lat 70-80. XX wieku. Od tego czasu zmienił się obraz typowego pieszego. Zachodzi zatem pytanie: czy w związku z tym prędkości pieszych uległy również istotnej zmianie? W celu odpowiedzi na tak postawione pytanie wykonano badania ruchu pieszych podczas przechodzenia przez jezdnię w rzeczywistych warunkach ruchu miejskiego. Określono zakres, w którym zawierała się prędkość pieszych oraz podjęto próbę sparametryzowania przebiegów czasowych prędkości do zastosowania w typowych analizach przestrzenno-czasowych wypadku z udziałem pieszego.

Pedestrian velocity is the parameter necessary in majority of traffic accidents reconstruction analysis results with pedestrian. Available literature refers to pedestrian velocity researches from the ‘70s and ‘80s of the twentieth century. Since then the characteristic of a typical pedestrian has significantly changed. The following question is appearing: Have the pedestrians velocities significantly changed because of this fact? In the destination of the answer to the question investigations of pedestrians motion during crossing the road in real urban traffic conditions were prepared. It was defined the range in which the pedestrians velocity was included and there was made the attempt to parameterize the temporal courses of velocity to be applied in typical spatio-temporal analyses of traffic accident with the participation of the pedestrian.
